- ADJUSTABLE SHADE-ROLLER SUPPORT.

Specification of Letters Patent.

Patented Feb. 24, 1914.

Application filed March 28, 1913. Serial No. 757,330.

To all whom it may concern:

Be it known that I, HERMAN J. DRUFFEL, a citizen of the United States,and a resident of the city of Chicago, county of Cook, and State ofIllinois, have invented certain new and useful Improvements inAdjustable Shade-Roller Supports, of which the following is aspecification.

My invention relates to improvements in means for adjustably supportingwindow shades and has for its object the production of a supportingmechanism of this character which will be of simple and economicalconstruction and eiiicient in use.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which Figure 1 isa front view of a window frame in conjunction with which isarranged ashade supported by mechanism embodying my invention, Figs. 2 and 3 arevertical transverse sections taken through said win dow frame looking inopposite directions, Fig. 4: is an enlarged detail side elevation of theupper end portion of one of the guide members included in theconstruction, Fig. 5 is a front elevation thereof, Fig. 6 is a Viewsimilar to Fig. 5 of another of the guide members embodying myinvention, Fig. 7 is a section taken on line a;00 of Fig. 6.

The preferred form of construction as illustrated in the drawingsespecially Figs. 1 to 7, inclusive, comprises elongated guide members 1of channel construction which are arranged at the inner sides of thevertical bars or side members of the window frame 2 at the upper end ofthe latter, said guide members being rigidly secured in position byscrews or other suitable fastening means. Slidably mounted in the guidemembers 1 at the respective sides of the window frame are supportingmembers 3 and 4 respectively, also preferably of channel form as shownin Fig. 7. The sides oft-he channel members 1 extend over the lateraledge portions of the members 3 and 4 serving to lock the same inposition in said guide members permitting however of free verticalmovement. The supporting members 8 and 4 are provided with slots 5 and 6respectively for engagement with the t-runnions provided at therespective ends of the shade roller 7 The slot 5, which engages with thesquared or flattened trunnion of the shade roller opens laterally asshown at- 5 to permit of engagement and disengagement of the trunnion,when said opening 5' of said slot 5 is in registration with the opening5 formed at the upper end of the corresponding guide member by cuttingaway the adjacent side thereof, as clearly shown in Figs. 4 and 5.Except when the member 3 is at its upper terminal of movement in thecorresponding member 1, the side of said channel adjacent to the opening5 of the slot 5 will serve to close said slot and thus insure againstaccidental displacement of the roller trunnion from said slot. Thesupporting members 3 and at are supported in the guide members 1 bymeans of flexible cords 8 and 9 respectively. Said cords 8 and 9 passupwardly from said supporting members over channel rollers 10 and 11mounted in the upper ends of said guide members, the cord 8 passingacross the upper end of the window frame adjacent the under side of theupper bar thereof and passing also over the roller 11 as clearly shownin the several views, said roller being of the double type, as clearlyshown in Fig. 6 in order to accommodate both cords. Said cords passdownwardly from said roller, the same being connected with a ring 12which is adapted for engagement with any one of a plurality ofvertically spaced headed studs 13 which are secured to the window frameas shown. lVith this arrangement it will be seen that the cords S and 9will serve to support the members 3 and 4 and hence the shade rollerwhich is carried thereby. Vertical adjust ment of the shade roller maythus be effected by simply manipulating the ends of said cords connectedwith the ring 12 and said shade roller may be fastened in its positionof vertical adjustment by engagement of said ring with the correspondingstud 13. Said studs are headed as shown in order to prevent accidentaldisengagement of the ring 12 therefrom.

With aconstruction then as set forth a shade roller may he supported atany vertical position desired and to which position the same may beadjusted and locked with ease and expedition.

While I have illustrated and described the preferred forms ofconstruction for carrying my invention into effect, these are capable ofvariation and modification without departing from the spirit of theinvention. I, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come within the scope of the appendedclaims.

Having described my invention what I claim as new and desire to secureby Letters Patent is:

1. The combination with a window frame, of vertically disposed channelguide members secured thereto at opposite sides there of; membersslidably mounted in said guides and having slots for engagement with thetrunnions at the ends of the shade roller, one of said slots openinglaterally, the adjacent side of the corresponding channel serving toclose said slot to prevent displace ment of the trunnion therefrom; andmeans for adjusting said supporting members in said guides and forlocking the same in positions of adjustment, substantially as described.

2. The combination with a window frame, of vertically disposed channelguide members secured thereto at opposite sides thereof; membersslidably mounted in said guides and having slots for engagement with thetrunnions at the respective ends of the shade roller, one of said slotsopening laterally, the adjacent side of the corresponding channelserving to close said slot to prevent displacement of the trunniontherefrom, a portion of said channel side being cut away forregistration with said slot to permit of disengagement of said trunnionfrom said slot; and means for adjusting said supporting members in saidguides and for locking the same in positions of adjustment,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

HERMAN J. DRUFFEL.
